Thought replacing trap under sink would be simple - help?

I should preface this by saying that I am aware I made a mistake here and also that the previous owners of my house did a lot of projects themselves that we have found to be done incorrectly.

Anyway, I had a slow draining bathroom sink and decided to clean out gunk that had built up. I disconnected the sink and removed the tailpiece as well as the trap. There was so much old and nasty debris that I decided it would be easier to just replace rather than clean.

Apparently this was a mistake.

I have attached a photo of the piece that I removed the trap from.

I am clearly a novice at this, but what I have found is that the traps they sell at big box stores seem to have threads on them and the expectation is that the piece shown in the photo would slot inside and have a tightening ring that screws onto the traps threads.

Clearly this is not possible with what I have here.

So the question: What is the right trap piece I need to replace?

Back off that chrome nut near the wall and slide the whole assembly out of the wall.

That seems like a much bigger job than expected - is there not a female to male converter or something I can use to just simplify..?

It looks like a normal back half of a ptrap to me, mock up how it was and send us a wider shot of what you are looking at. I fail to see an issue given the close up picture you attached. 1-1/2 in. PVC DWV Hub x Hub P-Trap-C4895HD112 - The Home Depot

@czizzi

Thank you for the link! Lowes did not carry traps with unions like that - (threads were on the trap itself).

I tried the piece from HD and it is a hair too big. Are the thread diameters unique to the manufacturer? I know the pipe is the right size but the threads dont' line up - just very close but a slight bit too big

The pictured trap is the wrong one for a sink. Here is the P trap you need along with a trap adapter.

Everbilt 1-1/4 in. Plastic P-Trap-C9700B - The Home Depot

1-1/2 in. x 1-1/4 in. PVC DWV Hub x SJ Trap Adapter-C48017HD112114 - The Home Depot

The adapter glues onto the straight 1 1/2" pipe coming from the wall and accepts the 1 1/4" trap. The tailpiece on the sink should also be 1 1/4". With this setup the new trap will be forever removeable for cleaning and/or future replacement just by loosening the plastic nuts.

@CasualJoe
What is the difference in using a 1-1/4 vs 1-1/2 trap?
To use the piece you sent, I would need to cut the pipe coming out of the wall, is that correct?

Yes just cut the ellbow off coming out of the wall.

Glue on a trap adapter 1 1/2" ( Dry fit all first to be sure trap lines up with tail piece.

And use trap as joe shows 1 1/2...

I guess I'm just confused - why is 1 1-4" superior to 1 1-2"
Basically, do I need to include the adaptor or can I just go directly for the same piece with a 1 1-2" trap with union?

Edit: Also the reviews for that trap are terrible - everyone says it leaks because the fittings are poor

The trap shown was for the image only. 1" is used in the bathroom for lavatory sinks. 1" is used in kitchens.

Hi,As said before you cut off the old p trap install a 1 1/2 adapter. You then buy a PVC Or ABS p trap
Kit. When you open you will find a bunch of plastic washers. One will be different it will have a smaller hole that will fit on the tail piece of your lav sink, then put the system together. If you are doing a kitchen sink put that different washer in your junk drawer and use the big washers.
Good Luck Woodbutcher

Just an FYI, I never used an 1 1/4 trap in my life...

I have, a chromed brass 1 1/4" trap, but it was many years ago. I much prefer a PVC trap.

All of the PVC traps I see in the big box mega-mart homecenters are 1-1/2 with both a 1-1/2 AND a 1-1/4 inch slip nut and washer to fit either size tailpiece.

I ended up cutting the pipe coming out of the wall and gluing a new adaptor piece with a new p trap from home depot (the one shown previously). I used a 1-4" to 1-2" converter and reconnected everything and it all looks great and no leaks!
Thanks for the helps - this was much easier than expected
